Add support for suggesting Async suffix in a method name

[DevEngineReq]

ReCommended-Extension should suggest me to add the Async suffix to an asynchronous method name

[michael-damatov]

"Asynchronous method" is a bit confusing here:

• a method with the async modifier
• an awaitable method (that returns a Task, Task<T>, ValueTask, ValueTask<T>, or even IAsyncEnumerable<T>). Such a method don't have to have the async modifier to be awaited. You can also have awaitable properties (that are of the types listed above).

The effort of adding such a feature to the "ReCommended Extension" definitely outweighs the potential benefits. Please, take a look at other extensions.

Side note: Historically, the "Async" suffix was added to new awaitable methods (that return Task or Task<T>) to distinguish between older non-awaitable methods. When designing new classes, which consist only of awaitable methods, what is the added value making all method names simply longer?
